Abstract:

We define a family of a (non-principal) ultrafilter on {\mathbb N}, i.e. a point which are very far from P-points. We first under reasonable conditions, prove its existence. In a continuation we shall prove that such a point may exist while no P-point exists. - Version 2023-05-04_3 (22p) published version (13p)
